The SF Examiner also points out a seven-minute video produced by the City taking Prop D from both angles.

In the video, a proponent says the measure will "bring people back to Mid-Market," which will inevitably bring businesses back, creating an "exciting, vibrant environment" and a "seamless connection along Market Street" from the Civic Center to the Ferry Building.

Opponent? "Private commercial interests" will come in to dump ads on Market, giving a "large Times Square-esque feeling to a historic arts neighborhood."
